Dimensions
Die Springs DIN & ISO are arranged in groups according to diameter. However, with this system, die springs with the same mounting dimensions can be selected in accordance with different load requirements. This increases the durability of stamping, bending and other dies. Each group of die springs is arranged according to a color code system, in order of increasing load.
Materials
Chromium alloys for highly dynamic applications at high temperatures.
Original Raymond ®Die Springs.
High-quality chrome-vanadium steel according to ISO-10243.
Heat
Maximum Force
Die springs are designed for situations where considerable loads are applied in a very confined space, particularly in the case of press dies. The use of chrome alloys permits maximum loads to be combined with a long service life.
ISO-10243 Standard
The solid length is approx. Ln; here the maximum forces are achieved.
For frequencies greater than 1000 strokes/minute, the following values should be observed in the case of springs with the designation 0R....
Green: 25% to 30% compression
Blue: 20% to 25% compression
Red: 15% to 20% compression
Yellow: max. 15% compression
Springs with the designation 0ST... have the following color codes and load types
Medium loads = Blue
Medium heavy loads = Red
Heavy loads = Gold
Extra heavy loads = Green
